# Lecture content and homework Math 454, Fall 2007

The course will emphasize the art of counting.  It begins with chapter 2 and then jumps to part II.  The aim is to cover chapters 5, 6, and 7.  (Chapter 8 would be a nice conclusion to this theme, but it requires some acquaintance with abstract algebra.)  Some fragments of chapter 3 may be introduced as needed.  If we complete this, we will move into chapter 9. Here is the syllabus that evolved on the Sakai site.

I intended to assign 4 and 8, but a previous entry was copied without being cleared for the new assignment. Problem 4 is hard enough, and part of problem 8 should be done as part of a complete solution to problem 4.)
